LAMINATED BOARD AND METHOD OF HAKIN G SAME.
Application flled'AprH 21, 1927. serial no. 185,442.
This invention relates to structural materials and its object is to provide a manufacture of this class combining in a greater degree than heretofore certain desirable qualities such as strength,lightness, low cost and easy workability adapting it for use in a variety of situations where such qualities are important, for example in air-craft construction.
Of the accompanying drawings, Fig. 1 is a'pers ective view showlng a composite-board embo ying my invention, with a portion of one of the metallic facing layers stripped back at a corner thereof.
Fi 2 is a cross-section of the composite boar Referring to the drawings, 10 is a layer of cellular material characterized by substantail firmness or rigidity, such as sponge hard rubber, obtained by incorporating in a rubber compound suflicient sulfur to vulcanize it to a hard condition, together with a suitable blowing agent, and an accelerator if desired,
and then vulcanizing forthe necessary length of time.
This cellular layer is faced on atleast one side with a thinsheet'of metal, and in this instance I have shown two such metal facing sheets 11 on opposite sides of the layer 10. While variousmetals such as steel, zinc, copper, or brass or other alloy may be employed,
.I prefer, for uses where extreme lightness is a primary consideration, to employ aluminum, under which term are included alloys of aluminum such as duralumin.
It is essential that the metallic facings 11 shall be bonded to the cellular hard rubber 10 in such manner that a durable adhesion isobtained, capable of remaining permanent under bending, denting and other stresses to which the material is subjected in use, and also adapted to withstand the operations which may be employed in fabricating the material into structures, attaching it to other parts, etc., such' as sawing, drilling, nailing, screwing or riveting. I
Generally speaking, the direct adhesion of hard rubber to plane metal surfaces is very weak, and this is particularly true in the base of aluminum and its alloys. The composite structure therefore includes a bonding or cementing layer 12 between the cellular hard rubber layer 10 and each of the metal facing layers 11, these bonding layers being flexible or non-brittle and of such nature as to adhere both to the rubber and the metal. The bondmg layer maybe applied in solution. or otherwise. While a rubber or other cement adapted to cure to a semi-hard condition might be employed, prefer toemploy for the cementmg or bonding substance a tough, balata-like, thermoplastic, artificial derivative or isomer of rubber prepared by reacting undissolved rubber under the influence of heat with p-phenol sulfonic acid or equivalent reagent, as described in Example 2 of patent to H. L. Fisher, No.1,605,180, dated November 2, 1926.
The metallic facing sheets 11 may be applied to the layer 10 either before or after the latter has assumed its cellular, rigid condition, and the stickyfaced metal sheet is then applied to the rubber sheet and caused to adhere thereto, preferably with the aid of heat and pressure. The bonding layer may itself be of a composite nature, the first part being baked on the metal, in which caseit is preferred to incorporate in the balata-like, rubber reaction product for the baking layer a small proportion of a. drier such as the oleate orlinoleate of manganese,lead or cobalt; and the second partheing said reaction product without the drier, laid thinly over the baked layer.
When the metallic facing sheet or sheets are applied to the rubber sheet before vulcanization of the latter, the rubber compound can be calendered or otherwise laid upon the sticky-faced metal sheet, overlaid with a similar. metal sheet if the board is to be armored on both sides, the article'pl'a ced between steam-heated press platens with sufficient clearance between it and the upper platen to allow for the desired ultimate thickness, and there vulcanized, the rubber being sponged b the blowing agent contained therein an the heat and pressure causing a firm adhesion between it and the facing sheets through the bonding layers.
The result is a composite or lammated board of great lightness and strength peculiarly adapted for use in aircraft construction or in other situations where these qualithe advantages of wood and'many superiorities thereover. It can be readily sawed with- 'ties are desired. This material has most of ber united therewith by a flexible, com

I The described embodiment may be considerably varied without departing from my) invention as defined in the appended claims.
a I claim:
1. Laminated structural material comprising a layer of cellular hard rubber, and a metal sheet united therewithby a flexible bond.
2. Laminated structural material comprising a layer of cellular hard rubber, and a metal sheet united therewith by a bonding layer consisting of a heat-plastic reaction product of rubber.
- 3. Structural material comprising a body of cellular hard rubber, and a metal facing sheet united therewith consisting of a balata-like, heat-plastic, artificial isomer of rubber.
' 4. Structural material comprising a body of cellular hard rubber, and a metallic memosite bond, said bond consisting of a part aked It is weather-e by a bonding layer upon the metal and another part uniting the first-said part t6 the rubber.
5. Laminated structural material comprising a layer of cellular hard rubber located between two metal sheets and united thereto by flexible bonding layers.
6. Laminated structural material comprising a layer of cellular hard rubber located between two sheets of aluminum and united thereto by flexible bonding layers.
7 Laminated structural material comprising a layer of cellular hard rubber located between two sheets of aluminum and united thereto by flexible bonding layers composed of a balata-like, heat-plastic artificial isomer of rubber.
8. Laminated structural material comprising two facing sheets of metal and a layer of hard sponge rubber lying between them and firmly united with each of the sheets in extensive face-to-faee relation.
9. Laminated structural material comprising a facing sheet of metal and a layer of hard sponge rubber united therewith in extensive face-to-face relation. 1
In witness whereof I have hereunto set my hand this 19th day of April, 1927.
